<p>Capsule (1) for the preparation of a beverage in a centrifugal extraction device (50) by feeding liquid in the capsule and rotating the capsule along a rotational axis (I) in the device to produce centrifugal forces on the liquid, wherein the capsule (1) comprises containment walls forming an interior cavity (2) containing beverage ingredients (3); said containment walls comprising a lid (4) and a side wall (5) extending substantially revolutionary around a central axis (I) and a peripheral flange (8) extending peripherally in radial direction to said axis (I), said flange (8) comprising an annular base (9) extending outwardly and a valve means (10) connected to said annular base, said valve means (10) extending in a direction (A) transversal to said radial direction (B) and being configured with at least one deflectable valve portion (11) which deflects for leaving a transversal passage upon the centrifugal pressure exerted by liquid flowing thereon when the capsule is rotated about the axis (I) during the centrifugal extraction wherein the peripheral flange (8) forms an extension part of the side wall (5) and is independent from said lid (4).</p> |
